ECS-SS Manual Hydraulic Crimper (CR20XX) for Coin Cells, ESSCCMHC

For manual coin cell assembly, a hydraulic manual crimper is the standard "workhorse" for laboratory research. It uses a hand-pumped hydraulic jack to provide the high, uniform pressure needed to deform the coin cell gasket and create a gas-tight seal.

The critical specifications for the manual hydraulic crimper are: (1) Die Compatibility: Most units come with a universal die for CR2016, CR2025, and CR2032. Optional dies are required for larger cells like CR2450 or CR3032. (2) Sealing Pressure: For CR20XX series cells, the recommended sealing pressure is typically 800–1000 psi (approximately 50–70 kg/cm2). (3) PTFE Anti-Corrosion Core: High-quality crimpers use a PTFE core to prevent the coin cell from short-circuiting against the steel die during the crimping process. (4) Weight: If you plan to move the unit in and out of a glovebox frequently, look for "Compact" or "Lite" versions which weigh 12–25 kg, compared to standard versions which can reach 40 kg.
